Crucible Price in Bangladesh 2026 – Buy Genuine Lab Crucibles

The Crucible price in Bangladesh ranges from ৳500 to ৳1,100 at astzbd.com, with genuine Vitreosil silica crucibles available across 25ml, 50ml, and 100ml capacities. A crucible looks like a simple vessel on the surface, but the wrong material or capacity can crack under heat or throw off your sample weight entirely, so getting the specification right matters more than most first-time buyers expect.

Crucible Overview – Reliable Vessels for High-Temperature Lab Work

A crucible is a small, heat-resistant container used to hold samples during high-temperature laboratory processes like ignition, ashing, and gravimetric analysis. Whether you’re running routine chemistry coursework or precise materials testing, the Crucible price in Bangladesh reflects a tool built to survive repeated exposure to extreme heat without cracking, contaminating your sample, or losing dimensional accuracy.

How Is a Crucible Used in the Lab?

Heating, Ignition & Ashing Process

A crucible holds the sample directly over a Bunsen burner flame or inside a muffle furnace, withstanding temperatures that would destroy standard glassware while the sample undergoes ignition or ashing.

Gravimetric Analysis Application

Precise, repeatable weight measurement before and after heating is central to gravimetric analysis, and a crucible’s consistent mass and low porosity keep that measurement accurate across multiple heating cycles.

Why Material Choice Affects Performance

Different crucible materials expand, contract, and resist chemical attack differently under heat, so choosing the right one for your specific application prevents cracking, contamination, or inaccurate results.

Types of Crucibles We Offer

Ceramic/Porcelain Crucible

Porcelain crucibles offer strong general-purpose performance for routine heating, ignition, and educational lab work, with good mechanical strength at a lower cost than specialty materials.

Silica Crucible

The Silica Crucible 25ml Vitreosil, Silica Crucible 50ml Vitreosil, and Silica Crucible 100ml Vitreosil offer excellent thermal shock resistance, making them well suited for applications involving rapid heating and cooling cycles.

Platinum & Metal Crucible

For highly specialized analytical work requiring extreme chemical inertness, platinum crucibles resist attack from aggressive fluxes and acids that would degrade ceramic or silica alternatives.

Crucible with Lid vs Without Lid

A matching lid reduces contamination and heat loss during heating, while lidless crucibles suit applications where sample exposure to open air is part of the process itself.

Key Features to Look for in a Crucible

Capacity (mL)

Match capacity to your sample volume — the Vitreosil range covers 25ml for small-sample analysis up to 100ml for larger batches, so choose based on your typical protocol.

Maximum Temperature Resistance

Silica crucibles like the Vitreosil series handle extreme thermal cycling reliably, an important factor if your work involves repeated rapid heating and cooling rather than steady, constant temperatures.

Form Type (Low Form vs Tall Form)

Low-form crucibles suit controlled heating and small-sample analysis, while tall-form designs accommodate applications needing more vertical clearance during the heating process.

Glazing & Surface Finish

A properly finished surface improves chemical resistance and makes cleaning easier after each use, extending the crucible’s usable lifespan across repeated heating cycles.

Wall Thickness & Porosity

Uniform wall thickness and low porosity ensure mechanical strength and prevent sample loss through the crucible walls during high-temperature exposure.

Lid Fit & Contamination Protection

A well-fitted lid, where included, helps reduce contamination and moderates heat loss, protecting both the sample and the accuracy of your final measurement.

Why Crucible Quality Matters for Accurate Lab Results

A cracked or contaminated crucible doesn’t just risk sample loss mid-experiment — it can silently skew a gravimetric result by trapping residue from a previous heating cycle or introducing microscopic material loss through hairline fractures. This is exactly why the Crucible price in Bangladesh for a genuine Vitreosil unit is worth paying over an unverified alternative, since consistent material quality protects both your data and your budget for repeat testing.

Ceramic vs Silica Crucible – Which One to Buy?

If your work involves steady, controlled heating for general or educational purposes, a ceramic crucible covers the need affordably. For applications with rapid temperature swings or demanding analytical precision, the Vitreosil silica range holds up more reliably over repeated cycles.

Crucible Price in Bangladesh

The current Crucible price in Bangladesh at astzbd.com is ৳500 for the Silica Crucible 25ml Vitreosil, ৳750 for the Silica Crucible 50ml Vitreosil, and ৳1,100 for the Silica Crucible 100ml Vitreosil.

What Affects the Price (Material, Capacity, Brand)

Capacity is the primary price driver within the same material line — a larger 100ml crucible costs more to manufacture than a compact 25ml unit. Material choice matters too, since silica and specialty materials like platinum command a premium over standard ceramic for their superior thermal shock and chemical resistance.

Why Buy Genuine Crucibles from astzbd.com

astzbd.com stocks genuine Vitreosil silica crucibles with consistent quality control, protecting you from unverified alternatives that may crack unpredictably under heat or introduce contamination into sensitive analytical work.

Who Should Buy a Crucible?

Chemistry & Analytical Labs

Gravimetric analysis and routine ignition testing depend on a crucible that holds consistent weight and resists cracking across repeated heating cycles.

University & Educational Institutions

Chemistry coursework and lab demonstrations rely on durable, reusable crucibles that can withstand regular student use without frequent replacement.

Materials Testing & Quality Control Labs

Ash content determination and material composition testing require crucibles with reliable thermal performance to ensure accurate, repeatable results.

Industrial & Metallurgical Applications

Sample preparation for metallurgical and industrial testing often demands crucibles capable of handling higher, more sustained temperatures than standard educational use.

How to Use a Crucible Safely – Quick Guide

1. Inspect the crucible for cracks or damage before each use
2. Place the sample inside and position the crucible securely over the heat source
3. Use crucible tongs, never bare hands, to handle the crucible during and after heating
4. Allow the crucible to cool gradually on a heat-resistant surface before touching or weighing
5. Clean thoroughly after each use to prevent residue buildup affecting future measurements

Crucible Care & Maintenance Tips

Store crucibles in a dry, padded location to prevent chipping or cracking from impact, avoid sudden temperature changes beyond the material’s rated thermal shock tolerance, and clean residue promptly after each heating cycle to maintain accurate future measurements. Regularly inspect for hairline cracks, since even minor damage can compromise both safety and result accuracy.

Crucible FAQ

What is a crucible used for in a laboratory?

A crucible is used to hold samples during high-temperature processes like ignition, ashing, and gravimetric analysis, withstanding heat that standard glassware cannot survive.

What temperature can a ceramic crucible withstand?

Quality ceramic crucibles typically withstand temperatures up to around 1050°C when used properly, making them suitable for most routine laboratory heating applications.

Can a crucible be reused after high-temperature heating?

Yes, crucibles like the Vitreosil silica series are designed for repeated reuse across multiple heating cycles, provided they’re inspected regularly for cracks or damage.

What’s the difference between low-form and tall-form crucibles?

Low-form crucibles suit controlled heating and smaller-sample analysis, while tall-form designs provide more vertical clearance for applications requiring it.

Does a crucible need a lid?

A lid isn’t always required, but it helps reduce contamination and moderate heat loss during heating, which can improve measurement accuracy in sensitive applications.
